<p>No work is performed while awaiting on the sleep future to complete. <code>Sleep</code>
|
||
operates at millisecond granularity and should not be used for tasks that

require high-resolution timers.</p>

<p>To run something regularly on a schedule, see <a href="../../tokio/time/fn.interval.html"><code>interval</code></a>.</p>

<p>The maximum duration for a sleep is 68719476734 milliseconds (approximately 2.2 years).</p>

<p>Canceling a sleep instance is done by dropping the returned future. No additional

cleanup work is required.</p>
